Core Viewpoint - The completion of the Guangxi Free Trade Zone Hongkun New Materials Benzene Hydrogenation Project marks a significant milestone as the largest single-unit benzene hydrogenation facility in China, filling a gap in the regional industrial chain and providing essential products like benzene and toluene for the Qinzhou petrochemical park [1][2]. Group 1: Project Overview - The project covers an area of 82,100 square meters and includes a 200,000 tons/year benzene hydrogenation unit and an 180,000 tons/year aromatics extraction unit [1]. - The project utilizes by-products of benzene from nearby coking enterprises and hydrogen from large petrochemical companies in the park to produce purified benzene, toluene, and heavy aromatics [1]. Group 2: Safety and Management - A "full-time penetration safety grid management system" was established, dividing the project into five safety responsibility zones to ensure 100% coverage of personnel, equipment, and processes [1]. - The project team identified and rectified 320 safety hazards, achieving a 100% rectification rate [1]. Group 3: Innovation and Challenges - The project team implemented an innovative "Party Building + Engineering" integration mechanism, establishing four Party responsibility zones and three Party pioneer posts to tackle technical challenges [2]. - The team worked continuously for 144 hours to successfully complete the installation of three large equipment pieces and maintained a welding pass rate of 98.05% for 176,000 inches of piping [2]. Group 4: Industry Impact - The project is seen as a new starting point for ensuring the safety of the high-end new materials industrial chain in South China, filling the gap in the benzene refining industry in the region [2]. - The facility is expected to create synergies with surrounding enterprises, enhancing the petrochemical industrial chain in the park [2].

中化新网讯 近日，由中国化学（601117）工程第四建设有限公司华北公司承建的广西自贸区宏坤新材 料粗苯加氢项目中交。作为目前国内单套规模最大、华南地区唯一的粗苯加氢项目，项目投产后将填补 区域产业链空白，为钦州石化园区提供苯、甲苯等产品。 据了解，该项目占地8.21万平方米，主要建设20万吨/年粗苯加氢装置，包含20万吨/年粗苯加氢单元、 18万吨/年芳烃抽提装置等。中国化学四化建相关负责人介绍，该项目利用周边省市焦化企业副产的粗 苯资源和园区内大型石化企业副产的氢气资源，对粗苯进行加氢精制，生产纯苯、甲苯、重芳烃等，产 品可供应至园区企业作为原料，驱动苯酚丙酮、己内酰胺等产业的协同发展。 施工过程中，项目部构建"全时域穿透式"安全网格管理体系，以物理区域与作业流程双维度划分5个安 全责任区，实现人员、设备、工序三重100%覆盖。责任区负责人每日带班督查，确保每项工作闭环落 实，累计整改高处作业防护缺失、临时用电违规等隐患320项，整改率达100%。 在项目攻坚冲刺阶段，项目部创新推行"党建+工程"融合机制，设立4个党员责任区、3个党员先锋岗， 组建2支党员突击队、1支青年突击队，领衔开展"大干80天 冲刺 ...
